Attest Sterilization Biological Indicator Vial Steam Compatibility

3M Attest biological indicators monitor the effectiveness of the steam sterilization process and provide results within 48 hours. The self-contained biological indicator for 250° F/121° C gravity and 270° F/132° C vacuum assisted steam cycles-consist of a Geobacillus stearothermophilus spore strip; sealed glass ampule with growth medium and a bromocresol purple pH indicator system; brown color coded cap with holes for sterilant penetration and a filter that acts as a barrier, and a process indicator on the label that changes from rose to brown when processed. After sterilization, the vial is crushed to join the growth media with the processed spore strip. The BI is incubated for 48 hours for a visual change readout. A color change to yellow indicates surviving spores and a positive result. Suggested application: Monitoring 250° F/121° C gravity and 270° F/132° C vacuum-assisted steam sterilization processes.

• Brown cap
• Self-contained indicators significantly reduce possibility of contamination, minimizing false positive and assuring more accurate results
